Groundwater poses a significant problem for civil engineers during construction. It is especially the case for foundations meant to go deep into the ground. Therefore, groundwater control techniques, such as wellpoint dewatering, are mandatory. Dewatering systems help lower the water table, thereby allowing deeper excavation and foundations. Consequently, it ensures the foundation remains dry and stable during flooding. This article looks at the benefits of a wellpoint dewatering system over other systems.
They Adapt to the Dewatering Needs of Most Sites
Project needs dictate the type of dewatering system civil engineers should use. For instance, a construction project that requires the foundation to go very deep is best dewatered with deepwells rather than with sump pumping. The reason is that sump pumping is only used for shallow excavations. However, such specialised systems are expensive since a construction company must buy or rent a different system for different projects.
A wellpoint dewatering system, on the other hand, can adapt to the needs of different projects. For instance, a single-stage wellpoint dewatering system is enough for shallow excavations. If a project requires deeper excavations, then a second stage can be installed. Additionally, wellpoint-dewatering systems can handle slow, low flows in silt sand and large flows in coarse sand.
They Lower the Cost of Excavation
Appropriate equipment and systems are critical in any construction project. Therefore, a dewatering system that performs well in different site conditions plays a critical role in lowering the cost of a project. Since a wellpoint dewatering system can adapt to different site needs, construction firms do not have to buy or rent other specialised systems. It lowers the total cost of the project significantly, which is every property developer's wish. Furthermore, it is cheaper to train workers to operate a single dewatering system compared to different systems.
They Can Be Speedily Installed
Construction projects have timelines that construction companies strive to meet or beat. However, constructions on groundwater tables are much more complex and require more time. Dewatering systems that are intricate and require a long time to install lengthen a project's timeline. A deepwell is a complex dewatering system that takes a long time to install. A wellpoint dewatering system is an exact opposite due to its ease of installation. All a civil engineer has to do is connect a series of small-diameter wells to a single header pipe with a suction pump. Addionally, the ease of installation requires only a lean workforce.
